Creating skyrmion-like spin structures in oxide thin film systems by strain doping

• Applicant: Dr. Andreas Herklotz
• Subject Area: Experimental Condensed Matter Physics
• Term: since 2020
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 441765851

It is the goal of this project to study the underlying mechanisms governing the creation and manipulation of non-collinear spin textures in oxide heterostructures using He ion implantation. In particular, the project aims at understanding the structure-property correlations of sykrmion-related phenomena and isolating key factors that drive enhanced functionality of these non-trivial states. For that purpose, a simple yet powerful approach will be used that introduces lattice strain in oxide thin film structures by low-energy He ion implantation. This “strain doping” approach offers a path to continuously tailor lattice strain in oxides with a controllability unmatched by standard strain engineering techniques. The project will contribute to a better understanding of skyrmion and magnetic bubble formation and will thus support efforts in bringing oxides to a deeper technological usage.
